The process of blind detection of a physical downlink control channel PDCCH in LTE is briefly described as follows, where a Control Channel Element (CCE) is the smallest element that carries PDCCH resources, and a control region is composed of a series of CCEs (CCEs).
The PDCCH blind detection range is defined by a search space, and the search space is divided into a public search space and a UE special search space. Search space Sk (L)Is defined as:CCE aggregation level L ∈ {1, 2, 4, 8}, for common search space, YkSearching from CCE (0-15); for UE-specific search spaces, Yk＝(A·Yk-1)modD，Y-1＝nRNTI≠0，A＝39827，D＝65537，nsRepresents a time slot number of 0 to 19; i-0, …, L-1, M-0, …, M(L)-1，M(L)Is the number of given PDCCH candidate sets (candidates) in the search space L.

N isRNTISpecifically, which type of RNTI is configured by a high-level signaling is selected, and a specific value is also specified by corresponding signaling and data. Values of RNTI are shown in table 2 below. Search spaces defined according to aggregation levelReferring to table 3 below, when the UE performs blind detection, the UE performs detection according to the DCIformat corresponding to the downlink transmission mode. The 16-bit Cyclic Redundancy Check (CRC) of each piece of downlink control information DCI is scrambled with the RNTI, and different UEs can configure different RNTIs to scramble the CRC, so that DCIs of different UEs can be distinguished.
TABLE 2
TABLE 3
In the LTE system, System Information (SI) is allocated to resources through DCIformat 1A/1C. The blind detection of SI is only done in the common search space and the CRC of the DCI of SI is scrambled with a unique SI-RNTI.
The DCI carries frequency domain resource information and modulation coding information, and is used to process data on the PDSCH. As shown in fig. 3, a data block sent to a physical layer by a Media Access Control (MAC) layer passes through nRNTIAfter Scrambling (Scrambling) of a random sequence, Modulation (Modulation) of a Modulation coding scheme indicated by the DCI, and data processing of subsequent layer mapping (Layermapping) and Precoding (Precoding), data is mapped to a frequency domain resource indicated by the DCI and transmitted.
Above the physical layer, there is an L2 layer, which is further subdivided into a MAC layer, a Radio Link Control (RLC) layer, and a Packet Data Convergence Protocol (PDCP) layer, as shown in fig. 4, where the PDCP layer is responsible for header compression of a robust header compression mechanism (ROHC) and security-related encryption, decryption, and integrity protection functions; the RLC layer provides functions of unpacking, packing and reliable retransmission of data; the MAC layer completes the mapping process from the logical channel to the transmission channel through scheduling. As shown in fig. 5, the MAC layer does not perform security protection on common logical channels such as a Physical Control Channel (PCCH), a Broadcast Control Channel (BCCH), and a common transport channel (CCCH), and performs security protection on dedicated logical channels such as a Dedicated Control Channel (DCCH) and a Dedicated Traffic Channel (DTCH), and maps the common logical channels to transport channels such as a Paging Channel (PCH), a Broadcast Channel (BCH), and a downlink synchronization channel (DL-SCH) after scheduling, and the transport channels are mapped to the PDSCH for transmission.
In an LTE-a carrier aggregation scenario, in a CONNECTED state (RRC-CONNECTED), a UE may perform data reception or transmission on more than two carriers at the same time, which has reached the effect of carrier aggregation. The downlink carrier is divided into a primary carrier (PCC) and a secondary carrier (SCC). The PCC is always kept in an activated state, and the SCC may activate or deactivate according to a change in a radio environment of a service or a carrier. When a UE needs to operate on a certain carrier, two parts of configuration information are needed: one is a radio resource common configuration part broadcasted in a system broadcast message, which is carried in a radio resource configcommon cell of an SIB2 in an LTE system, and common information of radio configuration carried in the common configuration is the same for all UEs; the other part is radio resource dedicated configuration for indicating UE-dedicated radio resource configuration information to be transmitted through a UE-dedicated radio channel. And after the UE obtains the radio resource common configuration and the special configuration, the UE can transmit data on a certain carrier.
Because the SCC has the feature of being activated and deactivated dynamically, the UE cannot monitor the broadcast on the SCC in real time at all times, for example: after the SCC is deactivated, when the common configuration information of the radio resources on the SCC is changed, the eNB notifies the UE of the updated system information of the relevant SCC through dedicated signaling for the purpose of power saving requirements of the UE and enabling the UE to perform data transmission as soon as possible after the SCC is activated. Because the contents of the system information updated by the SCC are all the same, when a plurality of UEs use the same PCC and SCC, a plurality of copies of the system information updated by the SCC are generated in the PCC and sent to different UEs through dedicated channels of different UEs, and these copies of the updated system information waste system resources and reduce bandwidth utilization.

Detailed Description
The basic idea of the invention is: for all UEs that need to receive common data, the eNB indicates in the corresponding DCI on the PDCCH that the allocated resource blocks are used to transmit common data; on the PDSCH, the eNB transmits common data by the resource blocks allocated by the DCI; the UE receives the common data from the PDSCH when the resource blocks allocated by the DCI are used to transmit the common data according to the indication in the DCI.
Here, the common data includes updated system information, multicast data, Multimedia Broadcast Multicast Service (MBMS) data, and the like.
The invention is further described in detail below with reference to the figures and the specific embodiments.
The present invention realizes a method for transmitting common data based on a physical downlink shared channel, as shown in fig. 6, the method includes the following steps:
step 601: the eNB adds the MAC header to the public data to be transmitted on the MAC layer to obtain a MAC PDU;
specifically, the eNB directly reaches the RLC layer without passing through the PDCP entity through common signaling in the RRC, the RLC layer submits the common data to the media MAC layer in a Transparent Mode (TM), the MAC layer adds a MAC header corresponding to a Common Control Channel (CCCH) to the common data, that is, the LCID in the MAC header is set to CCCH and 00000, and obtains a MAC pdu, which does not multiplex other logical channels or any UE-specific MAC command element (MAC ce);
step 602: for all the UEs needing to receive the common data, the eNB indicates the allocated resource blocks in the corresponding DCI carried on the PDCCH for transmitting the common data;
specifically, for all UEs that need to receive common data, the eNB carries corresponding DCI on the PDCCH, for example: sending DCI1 to UE1, sending DCI2 to UE2, scrambling through C-RNTI1 and C-RNTI2 to indicate that DCI1 is sent to UE1, and sending DCI2 to UE 2; the PRBs indicated in each DCI content should be the same, i.e. the content for resource block allocation needs to be consistent, and MCS, NDI, RV all need to be consistent, while indicating that the allocated resource blocks are used for transmitting common data;
the indication that the allocated resource block is used for transmitting common data may adopt a mode of setting a common data transmission flag or a common scrambling code identifier in DCI; when the mode of setting the public scrambling code identifier is adopted, the method may be based on the format of the original DCI, such as: on the basis of DCIformat1, DCIformat1A or DCIformat1C, extending a field of Nbit for setting a common scrambling code identifier (scrambleflag), indicating that a common scrambling code is used, indicating that the allocated resource blocks are used for transmitting common data, wherein N is an integer not less than 1, and generally N takes a value of 1;
further, in this step, the number of HARQ processes may also be set according to the process resources available to the UE.
Step 603: on the PDSCH, the eNB transmits common data by the resource blocks allocated by the DCI described in step 602;
specifically, on the PDSCH, the MAC layer of the eNB maps the MAC pdu containing the common data to the resource block allocated by the DCI in step 602 for transmission;
further, if the common scrambling code identity is set in step 602, the eNB scrambles the PDSCH using a common scrambling sequence;
the public scrambling sequence can be generated by a pseudo-random sequence algorithm, and different public scrambling sequences can be generated by setting different initial values; the initial value (C)init) Can be generated by the following equation (1):
in order to allow different UEs to receive the same common data, the eNB uses the same n with each UERNTIFor generating the same Cinit。
N isRNTIThe UE may be signaled by the eNB explicitly in advance, e.g., configured to the UE1 and UE2n by RRC signaling, respectivelyRNTI0xfff 4; alternatively, the eNB and the UE may agree through an implicit rule, such as default setting nRNTI0xfff 4; wherein, the configuration may also be configured according to Component Carriers (CCs), that is: configure n all UEs that can receive common data on CC1RNTI0xfff4, all UEs that can receive common data on CC2 are configured as nRNTI＝0xfff3。
Step 604: the UE receives the common data from the PDSCH when the resource blocks allocated by the DCI are used for transmitting the common data according to the indication in the DCI;
specifically, the UE receives DCI carried on the PDCCH, receives a MACPDU containing common data from the PDSCH when a resource block allocated by the DCI is used to transmit the common data according to an indication in the DCI, and parses the common data according to a structure of the MACPDU;
further, the UE generates a public scrambling code sequence which is the same as the eNB according to the public scrambling code identification in the DCI and the method for generating the public scrambling code sequence by the eNB, and the UE descrambles the PDSCH through the public scrambling sequence and receives the MACPDU containing public data;
further, the method also comprises the following steps: after receiving the common data, the UE sends response information of the corresponding HARQ protocol according to the CRC check result, that is: when the CRC check result is that the check is successful, namely the receiving is successful, the UE sends ACK to the eNB; when the CRC check result is that the check fails, namely the receiving is unsuccessful, the UE sends NACK to the eNB;
correspondingly, after receiving the NACK sent by the UE, the eNB retransmits the common data according to the set number of HARQ processes.
Based on the above method, the present invention further provides a system for transmitting common data based on a physical downlink shared channel, as shown in fig. 7, the system includes: eNB71, one or more UEs 72; wherein,

the eNB71 is further configured to add a MAC header to public data to be transmitted on a MAC layer to obtain a MAC protocol data unit;
correspondingly, the UE72 is further configured to parse the common data according to the structure of the MACPDU after receiving the MACPDU including the common data from the PDSCH;
the eNB71, configured to indicate the allocated resource blocks in the corresponding DCI on the PDCCH for transmitting common data, may be: the eNB71 sets a transmit common data flag or a common scrambling code flag in DCI;
further, the eNB71 is further configured to scramble the PDSCH with a common scrambling sequence after the DCI has set the common scrambling code identifier; the common scrambling sequence may be generated by a pseudo-random sequence algorithm by setting different CsinitDifferent common scrambling sequences will be generated; said C isinitMay result from equation (1), in order for different UEs 72 to all receive the same common data, eNB71 uses the same n with each UE72RNTIFor generating the same Cinit。

step 802: for all the UEs that need to receive the updated system information, the eNB indicates, in the corresponding DCI carried on the PDCCH, that the allocated resource blocks are used to transmit the updated system information, and configures the PDCCH on the DLSCC where the system information changes;
specifically, for all UEs that need to receive common data, the eNB carries corresponding DCI on the PDCCH, where the PRBs indicated in each DCI content should be the same, that is, the content for resource block allocation needs to be consistent, and the MCS, NDI, and RV all need to be consistent, and indicate that the resource block allocated thereto is used for transmitting updated system information; configuring the PDCCH on the DLSCC with changed system information;
the resource block allocated to the indication is used for transmitting updated system information, and a mode of setting a system information flag for transmitting update or a common scrambling code flag in DCI can be adopted;
step 803: on the PDSCH, the eNB transmits the updated system information by the resource blocks allocated by the DCI described in step 802, and configures the PDSCH on the DLSCC with changed system information;
specifically, on the PDSCH, the MAC layer of the eNB maps the MAC pdu containing the updated system information to the resource block indicated by the DCI and used for transmitting the updated system information; configuring the PDSCH on DLSCC with changed system information;
further, if the common scrambling code identity is set in step 802, the eNB scrambles the PDSCH using a common scrambling sequence;
the common scrambling sequence may be generated by a pseudo-random sequence algorithm by setting different CsinitDifferent common scrambling sequences will be generated; said C isinitCan be generated by equation (1); in order to allow different UEs to receive the same system information, the eNB uses the same n with each UERNTIFor generating the same Cinit。
Step 804: the UE receives the updated system information from the PDSCH when the resource block allocated by the DCI is used for transmitting the updated system information according to the indication in the DCI;
specifically, the UE receives DCI carried on the PDCCH, receives a MACPDU containing updated system information from the PDSCH when a resource block allocated by the DCI is used to transmit the updated system information according to an indication in the DCI, and parses common data according to a structure of the MACPDU;
further, the UE generates the same public scrambling code sequence according to the public scrambling code identification in the DCI and the method for generating the public scrambling code sequence by the eNB, and the UE descrambles the PDSCH through the public scrambling code sequence and receives the MACPDU containing the updated system information;
further, the method also comprises the following steps: the UE receives the updated system information, and sends response information of the corresponding HARQ protocol according to the CRC check result, that is: when the CRC check result is that the check is successful, namely the receiving is successful, the UE sends ACK to the eNB; when the CRC check result is that the check fails, namely the receiving is unsuccessful, the UE sends NACK to the eNB;
correspondingly, after receiving the NACK sent by the UE, the eNB configures the PDSCH on the DLSCC where the non-system information changes according to the set number of HARQ processes when MPn +1 arrives, and retransmits the updated system information.
Describing the present embodiment by way of example, as shown in fig. 9, a UE1 configures carriers for receiving or sending data as DLSCC1 and DLSCC5, a UE2 configures carriers for receiving or sending data as DLSCC2 and DLSCC5, a UE3 configures carriers for receiving or sending data as DLSCC3 and DLSCC5, and a UE4 configures carriers for receiving or sending data as DLSCC4 and DLSCC5, if the DLSCC5 needs to be updated, in MPn, for the UE1, the UE2, the UE3, and the UE4, the eNB indicates allocated resource blocks in corresponding DCI carried on the PDCCH for transmitting updated system information, transmits the updated system information by the allocated resource blocks, and configures the PDCCH and the PDSCH on DLSCC 5; the UE1, UE2, UE3, and UE4 respectively receive updated system information on the PDSCH using DLSCC5, and if the UE successfully receives the updated system information, send an ACK to the eNB; otherwise, since the UE is unaware of the radio configuration used by CC5 at MPn +1, the eNB configures the PDSCH on other DLSCCs where no system information update occurs when MPn +1 arrives.
For the UE1, it may select DLSCC1 where no system information update occurs, and retransmit the updated system information; for the UE 2; PDSCH may be selected to be configured on DLSCC2 where no system information update occurs; for the UE3, PDSCH configuration may be selected on DLSCC3 where no system information update occurs; for the UE4, it may choose to configure PDSCH on DLSCC4 where no system information update occurs.

specifically, for all UEs that need to receive common data, the eNB carries corresponding DCI on the PDCCH, where the PRBs indicated in each DCI content should be the same, that is, the content for resource block allocation needs to be consistent, and the MCS, NDI, and RV all need to be consistent, and indicate the resource block allocated thereto to transmit updated system information; configuring the PDCCH on the DLSCC of which the system information is not changed;
the indication that the allocated resource block is used for transmitting updated system information may adopt a mode of setting a system information flag for transmitting update or a common scrambling code flag in DCI;
step S103: on the PDSCH, the eNB transmits the updated system information by the resource block allocated by the DCI in step S103, configures the PDSCH on the DLSCC where the system information changes, and configures the PDCCH to use cross-carrier scheduling for the PDSCH;
specifically, on the PDSCH, the MAC layer of the eNB maps the MAC pdu containing the updated system information to the resource block indicated by the DCI and used for transmitting the updated system information; configuring a PDSCH on a DLSCC with changed system information, and configuring the PDCCH to use cross-carrier scheduling for the PDSCH;
further, if the common scrambling code identifier is set in step S102, the eNB scrambles the PDSCH using the common scrambling sequence;
the common scrambling sequence may be generated by a pseudo-random sequence algorithm by setting different CsinitDifferent common scrambling sequences will be generated; said C isinitCan be generated by equation (1); in order to allow different UEs to receive the same system information, the eNB uses the same n with each UERNTIFor generating the same Cinit。
Step S104: the UE receives the updated system information from the PDSCH when the resource block allocated by the DCI is used for transmitting the updated system information according to the indication in the DCI;
specifically, the UE receives DCI carried on the PDCCH, receives a MACPDU containing updated system information from the PDSCH when a resource block allocated by the DCI is used to transmit the updated system information according to an indication in the DCI, and parses common data according to a structure of the MACPDU;

further, the method also comprises the following steps: the UE receives the updated system information, and sends response information of the corresponding HARQ protocol according to the CRC check result, that is: when the CRC check result is that the check is successful, namely the receiving is successful, the UE sends ACK to the eNB; when the CRC check result is that the check fails, namely the receiving is unsuccessful, the UE sends NACK to the eNB;
correspondingly, after receiving the NACK sent by the UE, the eNB performs HARQ operation when MPn +1 arrives according to the set HARQ process number, that is: and at the moment, if the PDSCH is configured on the DLSCC where the PDCCH is located and the HARQ operation occurs on the DLSCC where the PDCCH is located, the UE can perform HARQ soft combining on the updated system information received from the PDSCH before and after MPn +1, so that the utilization rate and efficiency of air interface resources can be improved.
